摘要： The present invention revisits the architecture of IP routers based on the observations i) that the quality of open source routing software is getting to a point where it is usable in carrier grade networks and ii) that the major difference between switches and routers is in the software. Accordingly, the present invention proposes an alternative low cost high-performance router concept that a) uses commodity PC hardware with an open source software router for the control path and b) couples it with lower cost switching hardware by delegating packet forwarding to the switch. The present invention describes an implementation scenario and shows that the system according to the present invention is capable of handling full IP routing tables and the traffic requirements of a carrier aggregation network.

摘要： A method of enabling collaboration between an internet service provider (ISP) and a content distribution system (CDN) or between the ISP and an other ISP, comprises the steps of: gathering a domain name system (DNS) query; the ISP evaluating the DNS query wherein candidate hosts suitable for delivering content in accordance with the DNS query are collected; the ISP ranking the candidate hosts; the ISP providing a first list of the ISP-ranked candidate hosts; the ISP forwarding the DNS query to the CDN or to the other ISP; the CDN or the other ISP evaluating the DNS query wherein candidate hosts suitable for delivering content in accordance with the DNS query are collected; the CDN or the other ISP ranking the candidate hosts; the CDN or the other ISP providing a second list of the CDN-ranked or other ISP-ranked candidate hosts; matching the first list and the second list; and providing a matched list of ranked candidate hosts. According to the invention, by providing the first list of the ISP-ranked candidate hosts as well as the second list of the CDN-ranked or other ISP-ranked candidate hosts and by matching these two lists a client can obtain the matched list of matched candidate hosts. Thus, it is possible that the ISP efficiently collaborates with the CDN or the other ISP without transferring or unveiling critical information between each other.

摘要： A method of engineering traffic within a network comprises the steps of: configuring and controlling routing within the network and steering traffic through the network, wherein the steering of the traffic through the network is optimized based on routing control and configuration by evaluating interior gateway protocol weights, label switch paths within multiprotocol label switching and/or border gateway protocol properties. The method further comprises the steps of obtaining an ingress point at which content enters the network and obtaining an egress point at which content exits the network, wherein the steering of the traffic through the network is optimized based on routing control and configuration by evaluating the ingress point and the egress point.

According to the invention, by providing the first list of the ISP-ranked candidate hosts as well as the second list of the CDN-ranked or other ISP-ranked candidate hosts and by matching these two lists a client can obtain the matched list of matched candidate hosts. Thus, it is possible that the ISP efficiently collaborates with the CDN or the other ISP without transferring or unveiling critical information between each other.
